[PATCH 1/5] hw/sparc64/niagara: Pass available memory region size to add_rom_or_fail

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

In few commits we'll let rom_add_file_fixed() take a 'size'
argument holding the maximum file length that can be loaded
as ROM. In preparation, modify the Niagara machine, so the
generic change will be easier to review.
